⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Chloe returns to her empty office after Detective Thomas and Officer Doyle leave, having lied to them about her appointments. She feels the weight of the missing-girl case pressing on her—Lacey Beaulieu’s body was found in Cypress Cemetery, and another fifteen-year-old patient of Chloe’s has just been reported missing. Desperate to talk to someone but unwilling to burden Cooper or Daniel, Chloe drives to Riverside Assisted Living to visit her mother, Mona.

At the facility, Chloe notices the faded yellow buildings and feels guilt about neglecting her mother. She signs the guest book, chats with Martha at the front desk, and walks to Room 424. Inside, a nurse named Sheryl is brushing Mona’s hair. Chloe’s mother is in a minimally conscious state after a suicide attempt that occurred shortly after Chloe’s father was sentenced. Mona can move her fingers but cannot speak or walk. Chloe tells her about the missing girls and the eerie feeling of déjà vu—the police questioning her mirrors the investigation twenty years ago. She admits her paranoia might be tied to the anniversary of her father’s crimes.

After the conversation, Sheryl mentions that another man visited Mona recently—a “trendy looking” man with tortoiseshell glasses. Chloe realizes it is Aaron Jansen. She rushes to the front desk and demands to see the guest book from the weekend. Martha reluctantly hands it over, and Chloe finds Aaron Jansen’s signature from the previous day.

Character Development

Chloe Davis: This chapter deepens Chloe’s emotional isolation. She avoids reaching out to Cooper or Daniel because she fears their reactions—Cooper would worry and Daniel would drop everything for her. Instead, she turns to her mother, who cannot respond meaningfully. Chloe’s guilt over abandoning Mona is palpable; she acknowledges that keeping her in assisted living is easier than facing painful memories. Her decision to confess her fears to a silent listener shows her desperation for connection. The discovery that Aaron Jansen visited her mother without authorization stokes her anger and suspicion, pushing her toward a more confrontational state.

Mona Davis: Although physically present, Mona is almost a memory. Her minimal consciousness—blinking and finger-tapping—makes her a passive recipient of Chloe’s confessions. Mona’s backstory (the suicide attempt after Chloe’s father was convicted, the coma, the irreversible brain damage) reinforces how the father’s crimes devastated the entire family. Her presence haunts the chapter as a living consequence of past trauma.

Aaron Jansen: Though not present in the scene, Aaron looms large. His unauthorized visit to Mona—claiming to be a family friend—represents an intrusion into Chloe’s private world. The evidence of his name in the guest book confirms he is actively inserting himself into Chloe’s life, raising questions about his motives and his possible connection to the current disappearances.

Martha and Sheryl: These minor characters highlight the routine of the facility and the judgment Chloe perceives from caregivers. Martha’s comment about Mona having “all kinds of visitors” suggests that Chloe is not the only one keeping tabs on her mother.

Themes, Symbols, or Motifs

Memory and Déjà Vu: Chloe explicitly describes the current investigation as feeling identical to the past. The recurring sensation of reliving conversations from twenty years ago blurs the line between history and present, intensifying her paranoia. The anniversary of her father’s crimes acts as a trigger, making Chloe doubt whether the threat is real or imagined.
Guilt and Neglect: The assisted living facility itself symbolizes Chloe’s emotional neglect. The faded yellow buildings, missing blinds, and weed-choked sidewalks mirror her guilt about abandoning her mother. Chloe admits she left Mona there because it is easier than confronting the daily reminder of her father’s violence. Her confession to Mona—“Sorry for everything”—encapsulates a lifetime of regret.
Silence and Confession: Mona cannot speak, yet Chloe pours out her fears. The monologue becomes a one-sided confession, echoing the way Chloe felt as a child unable to truly share her trauma. The “locked box” of her mother’s mind cannot offer her the reassurance she craves, leaving her isolated even in the act of speaking.
Intrusion: Aaron Jansen’s unauthorized visit represents a violation of Chloe’s boundaries. He has stepped into her most private space—her relationship with her mother—without consent. This intrusion parallels the way the media and police have infiltrated her life since the bodies were found.

Why This Chapter Matters

This chapter deepens the central mystery by linking the current disappearances directly to Chloe’s personal history. The déjà vu motif suggests that either Chloe’s father has an accomplice still active, or that Chloe herself is being manipulated. Aaron Jansen’s appearance at the assisted living facility is the first concrete evidence that someone is deliberately inserting himself into Chloe’s orbit, and it raises the stakes: he has now interacted with a member of Chloe’s vulnerable family. The chapter also humanizes Chloe by exposing her guilt and isolation, making her a more sympathetic protagonist as she navigates the thin line between paranoia and legitimate fear.

Study Questions

1. Why does Chloe choose to visit her mother instead of talking to Cooper or Daniel?
Chloe believes that Cooper would worry too much and ask questions she does not want to answer, while Daniel would drop everything to rush to her side, which she feels would burden him. Her mother, being unable to respond, offers a safe, non-judgmental outlet where Chloe can speak her fears aloud without consequence.

2. How does the description of Riverside Assisted Living reflect Chloe’s emotional state?
The facility’s appearance—faded yellow paint, missing blinds, weeds in the sidewalk—mirrors Chloe’s guilt over neglecting her mother. She projects her own feelings of abandonment onto the building, describing it as “neglected” and “stained.” The physical decay symbolizes Chloe’s internal decay and her avoidance of past trauma.

3. What is the significance of Aaron Jansen having visited Chloe’s mother?
Aaron’s visit represents a direct intrusion into Chloe’s personal life. By claiming to be a family friend and signing the guest book, he has bypassed Chloe’s boundaries. The visit suggests that Aaron is actively monitoring Chloe or seeking information, and it hints that he may be connected to the disappearances, either as a copycat or as someone who wants to control Chloe’s narrative.
